Extender RF 2x
Extends a super telephoto lens’ focal length by 2x, so that an 800mm focal length, for example, becomes 1200mm. The extra reach makes it possible to get larger close-ups with the original camera resolution.
High Image Quality
A large aperture lens placed near the image sensor, the use of high-refractive, low-dispersion glass, and three cemented lenses that minimise air contact surface suppress field curvature, lens aberration and flare and ghosting, hence optimising corner-to-corner image quality.

Strength & Reliability
The lens features a vibration- and impact-resistant structure with a dust- and drip-resistant design, ready to withstand nature, motorsports, and other harsh professional and advanced shooting scenes.
Supporting heavy lenses is all in a day’s work for its robust, durable body.
Shooting at super-long focal lengths means a shallower depth-of-field, which can make focusing tricky. On the Extender RF 2x, built-in microprocessors communicate with the lens, achieving high-precision AF over an area as large as up to 80% x 80% (horizontal x vertical) of the focal plane* helping you to lock focus on your subjects more easily.
*With EOS R5 or R6 on the RF100-500mm f/4.5-7.1L IS USM. Actual AF area depends on the lens, extender, and camera body.
